For the improvement of ginsenoside bioavailability, the ginsenosides of fermented red ginseng by Phellinus linteus (FRG) were examined with respect to bioavailability and physiological activity. The polyphenol content of FRG ($19.14{\pm}0.50$ mg/g) was significantly higher (p<0.05) compared with that of non-fermented red ginseng (NFRG, $11.31{\pm}1.15$ mg/g). The antioxidant activities in FRG, such as 2,2'-diphenyl-1-picrylhydrazyl, 2,2-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid, and ferric reducing antioxidant power, were significantly higher (p<0.05) than those in NFRG. The HPLC analysis results showed that the FRG had a high level of ginsenoside metabolites. The total ginsenoside contents in NFRG and FRG were $41.65{\pm}1.53$ mg/g and $50.12{\pm}1.43$ mg/g, respectively. However, FRG had a significantly higher content ($33.90{\pm}0.97$ mg/g) of ginsenoside metabolites (Rg3, Rg5, Rk1, compound K, Rh1, F2, and Rg2) compared with NFRG ($14.75{\pm}0.46$ mg/g). The skin permeability of FRG was higher than that of NFRG using Franz diffusion cell models. In particular, after 3 h, the skin permeability of FRG was significantly higher (p<0.05) than that of NFRG. Using a rat everted intestinal sac model, FRG showed a high transport level compared with NFRG after 1 h. FRG had dramatically improved bioavailability compared with NFRG as indicated by skin permeation and intestinal permeability. The significantly greater bioavailability of FRG may have been due to the transformation of its ginsenosides by fermentation to more easily absorbable forms (ginsenoside metabolites).

This study compared the contents of ginseng prosapogenin depending on the extracting conditions of Ginseng Radix palva(Panax ginseng) to provide basic information for developing Ginseng Radix palva-based functional foods. Our findings show that the content of crude saponin peaked at 18 hours of extraction and when extracted twice at $100^{\circ}C$ (GRP-18). However, the content of total saponin reached its height at 6 hours of extraction at $100^{\circ}C$ (GRP-6) and when extracted twice. On the other hand, the content of ginsenoside $Rg_3$, $Rg_5$ and $Rk_1$ from Red and Black ginseng reached their heights at 18 hours of extraction, followed by 72 hours and 15 hours of extraction at $100^{\circ}C$. And at $100^{\circ}C$ the main prosapogenin of the content of Black ginseng ginsenoside $Rg_5$ and $Rk_1$ reached their heights at 18 hours of extraction, followed by 72 hours and 15 hours of extraction.

The purpose of this study is to develop a new preparation process of ginseng berry extracts having high concentrations of ginsenoside Rh1, Rg2, Rg5, F4, a special component of red and black ginseng. Chemical transformation from ginseng saponin glycosides to prosapogenin was analyzed by the HPLC. Extracts of ginseng (Panax ginseng) berry was processed under several treatment conditions including ultrasonication treatments. The content of total saponin reached their heights at 6 hr (UGB-6, 61.760%) of ultrasonication treatment, followed by 10 hr (UGB-10, 53.009%) and 9 hr (UGB-9, 50.652%) of ultrasonication treatment at $100^{\circ}C$. Results of those treatments showed that the quantity of ginsenoside Rh1 increased by over 15% at 10 hr of ultrasonication treatment at $100^{\circ}C$. The results of processing with UGB-10 indicate that the ultrasonication processed ginseng berry extracts that had gone through 10 hr treatments were found to contain the largest amount of ginsenoside Rh1 (15.358%), Rg2 (6.301%), Re (4.567%) and F4 (2.658%). In addition, UGB-6 contained ginsenoside Rg3 (13.632%) at high concentrations. It is thought that such results provide basic information in preparing ginseng berry extracts with functionality enhanced.

Panax ginseng C.A Meyer is frequently taken orally as a traditional herbal medicine in Asian countries. The major components of ginseng are ginsenoside, which are pharmaceutical activity. The six major ginsenosides, including Rb1, Rb2, Rc, Rd, Re and Rg1 account for 90% of total ginsenosides. Even though the minor ginsenosides, including Rg3, Rh2 and compound K has high pharmacetical activities, the price of minor ginsenosides is too high. Therefore we isolated the gypenoside V and made it converted to minor ginsenosides. In the plant Gynostemma pentaphyllum Makino, gypenosdie V was presented as dominant saponin (content about 2.4%), and was similar to protopanaxadol type ginsenosides such as ginsenoside Rb1. In this study, we confirmed that the coversion of gypenoside V to minor ginsenosides after using the various treatment such as heating, acid treatment, commercial edible enzyme, and lactobacillus. Consequently, we optimizied the transformation of gypenoside V to minor ginsenoside using Thin Layer Chromatography (TLC), High Performance Liquid Chromatography (HPLC), Time-of-flight Mass Spectrometry (LC/TOF/MS).

The aim of this study was to investigate the comparative growth characteristics and ginenoside contents of wild-simulated ginseng on different years (7 and 13-year-old) by monitoring soil properties of cultivation regions. Plant and soil samples were collected from 6 different cultivation regions. Soil organic matter (OM), total nitrogen (TN) and cation exchangeable capacity (CEC) were significantly higher in 13-year-old wild-simulated ginseng cultivation regions compared to 7-year-old wild-simulated ginseng cultivation regions. Growth characteristics of wild-simulated ginseng had shown significantly higher in 13-year-old wild-simulated ginseng compared to 7-year-old wild-simulated ginseng. Ginsenoside G-Rb1, Rb2, Rc, Rd, Re, Rf, Rg1 were significantly higher in 13-year-old wild-simulated ginseng than 7-year-old wild-simulated ginseng. According to the results of correlation analysis, soil OM, TN and CEC of the cultivated regions were positively correlated with the growth of wild-simulated ginseng. In addition, the root length of wild-simulated ginseng showed positive correlation with ginsenoside content. Hence, this study was able to investigate the correlation between growth and ginsenoside content of wild-simulated ginseng based on soil characteristics of the cultivation regions.

The experiment was carried out to study the effect of Korean wild ginseng adventitious root supplementation on the laying performance, egg quality, cytokine expression, ginsenoside concentration, and microflora quantity of Institut de selection Animale (ISA) brown laying hens at 24 weeks old. A total of 90 laying hens were subjected to a completely randomized design at three treatments, five repetitions and six laying hens per replicate. The experiments were divided by diets into the basic feed (CON), basic feed + 0.1% wild ginseng (WG1), and basic feed + 0.5% wild ginseng (WG2). The feeding trial was carried out over a duration of 12 weeks after an initial acclimation period of 2 weeks. Feeds and water were administered ad libitum in mash form, and light was available for 16 hours per day. At the end of study, henday egg production (HDEP), average egg weight (AEW), and egg mass (EM) were increased (p <0.05) in WG2 at week 12. Feed conversion ratio (FCR) was decreased (p < 0.05) in WG2 at week 12. The ginsenoside content in egg yolk was increased (p <0.05) in laying hens in the WG2 treatment at week 12. Relative expression of tumor necrosis factor alpha (TNF-α) was reduced (p < 0.05) in the WG supplemented diets at week 12. The fecal microflora quantity of Lactobacillus was increased (p < 0.05) in WG2 at week 8 to week 12, and Escherichia coli (E. coli) was significantly decreased (p < 0.05) in the WG2 at week 12. We concluded that the result observed in the HDEP, AEW, EM and FCR was due to an increase in ginsenoside content, leading to an improvement in the TNF-α, and fecal microflora quantity such as Lactobacillus and E. coli in the WG2 supplemented diets. We therefore recommend the use of WG at application level 0.5% per basal diet for optimum laying performance in layer hens.

Background: White ginseng consists of the roots and rhizomes of the Panax species, and red ginseng is made by steaming and drying white ginseng. While red ginseng has both polar and nonpolar ginsenosides, previous studies showed white ginseng to have only polar ginsenosides. Because nonpolar ginsenosides are formed through the manufacture of red ginseng from white ginseng, researchers have generally thought that nonpolar ginsenosides do not exist in white ginseng. Methods: We developed a simultaneous quantitative method for six nonpolar ginsenosides in white ginseng using reverse-phase high-performance liquid chromatography coupled with integrated pulsed amperometric detection. The nonpolar ginsenosides of white ginseng were extracted for 4 h under reflux with 50% methanol. Results: Using the gradient elution system, all target components were completely separated within 50 min. Nonpolar ginsenosides were determined in the rhizome head (RH), main root (MR), lateral root, and hairy root (HR) of 6-year-old white ginseng samples obtained from several regions (Geumsan, Punggi, and Kanghwa). The total content in the HR of white ginseng was 37.8-56.8% of that in the HR of red ginseng. The total content in the MR of white ginseng was 5.9-24.3% of that in the MR of red ginseng. In addition, the total content in the RH of white ginseng was 28.5-35.8% of that in the HR of red ginseng Conclusion: It was confirmed that nonpolar ginsenosides known to be specific components of red ginseng were present at substantial concentrations in the HR or RH of white ginseng.

Fuiarium solani 와 Phytophthora cactorum 이 인삼 사포닌 성분에 어떠한 영향을 미치는가를 알기 위해서 각 첨가배지에서의 균사생육과 접종된 인삼분말의 사포닌 분석실험으로 다음과 같은 결과를 얻었다. Fuiarium solani는 수삼의 물추출물 농도에 따라 생육이 억제되었으며 조사포닌 20ppm 첨가까지 생육이 촉진되었으나 50ppm이상에서는 불규칙적인 생육 억제효과가 있었다. 그리고 nystatin은 농도에 다라 생육을 억제하였다. Phytophthora cactorum은 수삼의 물추출액, 조사포닌의 농동에 따라서 생육은 촉진되었으며 nystatin은 생육에 영향을 미치지 않았다. F. solani 및 P. cactorum 으로 접종된 인삼분말은 ginsenoside Ra, Ro peak가 나타나지 않았으며 F. solani에 의해 PD 계 ginsenoside가 3.0% 증가되고 PT계 ginsenosides는 34.9% 감소되었다. P. cactorum의 경우는 PD 계 ginsenoside가 21.1% 증가, PT계 ginsenosides는 23.5% 감소하였다. 두 균주에 의해 PD, PT계 ginsenoside의 변화가 다르게 나타났지만 PD/PT비는 동일하게 58.4%씩 각각 높아졌다. 인삼의 총 사포닌 함량은 F. solani에 의해 17.8%, P. cactorum에 의해서 2.5%씩 각각 감소하였다.

인삼의 생장에서 염류의 집적은 우량 인삼의 생산에 많은 장애요인이 되고 있다. 본 연구에서는 순계 분리된 인삼의 우수 계통으로부터 NaCl 처리에 따른 생장율 조사와 ginsenoside의 생산에 미치는 영향을 조사하였다. 선발된 모상근(KGHR-8)으로부터 ginsenosides의 함량에 미치는 NaCl의 최적 농도를 조사하기 위하여 30일간 배양한 결과 NaCl의 농도가 증가함에 따라 모상근의 생장은 감소하였지만, total ginsenoside의 함량은 0.24M NaCl 처리구에서 높은 증가를 가져왔으며 특히 광을 조사하여 배양한 결과 높게 검출되었다. 0.24 M NaCl 농도로 광상태하에서 함량은 61.7% 증가하는 양상을 나타내었다. (Table 1). 또한 모상근의 생장을 최적 상태로 설정하기 위해 two step culture 방법을 조사한 결과, 0.05M, 0.1M NaCl 처리시 모상근의 생장율은 각각 약 62%, 76% 감소한 반면, ginsenoside의 함량은 29%, 48% 각각 향상되었다. 모상근은 방어기작의 일환으로 NaCl을 elicitor로 인지하고 2차대사산물인 사포닌의 생산에 영향을 미치는 것으로 확인되었다.
